National Tire & Battery [NTB] review: tires

Beware, be very aware if purchasing anything from ntb. I purchased 4 sumitomo touring tires from ntb. The sumitomo website indicated their tires came with a one year manufactures warranty. So since i'm planning on trading this car in I didn't buy the life-time warranty from ntb for an addiitional $74.95 above the $67.96 they already charge for installaltion. So, tire goes flat at 70mph within the year. Ntb says tough luck. What about the 1 year manufacture's road hazard warranty from sumitomo. Sorry, that applies to every other sumitomo tire except the one we sold you which is only sold thru ntb! Bottomline, i'm screwed and will never buy another ntb product/service ever. I own 6 cars/trucks and spend about $1200 per year on tires; but never again from ntb! Note: you can go to sam's club and for only $15 per tire get what ntb charges $47.33 per tire for. Yes, that $15 price includes road hazard plus life-time balances and rotation and disposal. That's a total savings of $129.32 on a set of 4 tires!
